“…It is generally accepted that toxicity of metal‐containing NPs is mainly or at least partially due to the release of toxic metal ions. [ 67,68 ] The results of our previous short‐term hydroponic studies show the released Ce 3+ ions accounted for the phytotoxicity of ceria NPs. [ 24,27,69 ] Although hydroponic studies can provide valuable information on mechanisms of interactions between NPs and plants, soil studies are desirable to obtain a more realistic understanding of the fate and impact of NPs in the environment.…”

The release of metal ions may play an important role in toxicity of metal‐based nanoparticles. In this report, a life cycle study is carried out in a greenhouse, to compare the effects of ceria nanoparticles (NPs) and Ce3+ ions at 0, 50, 100, and 200 mg Ce kg−1 on plant growth, biological and physiological parameters, and nutritional value of soil‐grown common bean plants. Ceria NPs have a tendency to negatively affect photosynthesis, but the effect is not statistically significant. Ce3+ ionic treatments at 50, 100, and 200 mg Ce kg−1 result in increases of 1.25‐, 0.66‐, and 1.20‐fold in stomatal conductance, respectively, relative to control plants. Both ceria NPs and Ce3+ ions disturb the homeostasis of antioxidant defense system in the plants, but only 200 mg Ce kg−1 ceria NPs significantly induce lipid peroxidation in the roots. Ceria NP treatments tend to reduced fresh weight and to increase mineral contents of the green pods, but have no effect on the organic nutrient contents. On the contrary, Ce3+ ion treatments modify the organic compositions and thus alter the nutritional quality and flavor of the green pods. These results suggest that the two Ce forms may have different mechanisms on common bean plants.

Xu, Shi, Cheng, Ji, Jin, et al, 2017).

The effects of engineered nanoparticles on nitrification during biological wastewater treatment

Technological advancements in the past few decades have made it possible to manufacture nanomaterials at a large scale, and engineered nanoparticles (ENPs) are increasingly found in consumer products, such as cosmetics, sports products, and LED displays. A large amount of these ENPs end up in wastewater and potentially impact the performance of wastewater treatment plants (WWTPs). One important function of the WWTP is nitrification, which is carried out by the actions of two groups of bacteria, ammonia-oxidizing bacteria (AOB), and nitrite-oxidizing bacteria (NOB). Since most ENPs are found to have or are designed to have antimicrobial activities, it is a legitimate concern that ENPs entering WWTPs may have negative impacts on nitrification. In this paper, the effects of ENPs on nitrification are discussed, focusing mainly on autotrophic nitrification by AOBs and NOBs. This review also covers ENP effects on anaerobic ammonium oxidation (anammox).Generally, nitrifiers in pure and mixed cultures can be inhibited by a variety of ENPs, but stress response mechanisms may attenuate toxicity. Long-term studies demonstrated that a wide range of NPs could cause severe deterioration of AOBs and/ or NOBs when the influent concentration exceeded an inhibition threshold. Proposed mechanisms include the generation of reactive oxygen species, dissolved metals, physical disruption of cell membranes, bacterial engulfment, and intracellular accumulation of ENPs. Future research needs are also discussed.
